(sorry, I’m French, I’m using the translator)

Hello! I have a problem with an .ardour file : when I launch ardour via a terminal, and I load this file, it returns the error “Segmentation fault (core dumped)”

This file must have been corrupted during a backup. Is there a trick to make it work again? Could it be that some lines have been erased or have been copied incorrectly? There are several hours of work on this sale. I invited musician and singer friends. it will be hard to get them back…

Thank you for your help!
